Can you be a Marxist-Leninist without liking Stalin...

No one is denying that a lot of people died. Difference is Stalin didn't wage campaigns to exterminate "inferior races." Most of the deaths attributed to Stalin were part of efforts to rapidly modernize the Soviet Union to meet growing external threats (namely as the rise of fascism.) The Great Purges were likewise in the context of fears of fascist espionage and sabotage.

George Washington killed tons of people too yet most amerifats worship him. Simply "killing people" isn't enough to throw out a person's entire legacy. Also killing reactionaries isn't a bad thing.

Stalin was a fascist

Socialists cannot be fascist.

In fairness, many of those who died during collectivization were ordinary peasants. Also, in regards to the Great Purges, Khrushchev noted:

The same thing was repeated in the republics, e.g. "of the 644 delegates to the Tenth Georgian Party Congress in May 1937, 425 had been arrested and shot." (Amy Knight, Beria: Stalin's First Lieutenant, p. 84.)

You mean the truth? There is no evidence whatsoever of this "Stalin" you mentioned. No such man has ever lived.

Yes, Bordigists are such.

They're hardly Leninists.

Bordigists call themselves unorthodox Leninists. They do adhere to Leninism but reject democratic centralism.

In what ways do they adhere to Leninism besides paying lipservice to Lenin? Democratic centralism is one of the defining features of Leninism.
